Basically our target has a MIPS24KE host processor on
which Linux runs and a networking processor (NP) which
sits between the EMAC
Ralf,
thanks for the detailed information.
Anyway, it would be much easier to help you if we
knew what you are trying
to achieve with these functions.

Hi Geert,
Thanks for your repsonse.
In linux-2.6.18 (for MIPS24KE processor):
suppose if i want to do flush only then which API i
should use?
Similarly, if i want to do invalidation only which API
i should use?
Thanks again.
Regards,
Veerasena.

hi Geert,
here i mean 'flush' is 'write-back only'

`flush' is fuzzy
Hi Ralf,
Thanks for the reply.
Is there any problem if we use the below API's in
linxu-2.6.18
- dma_cache_wback_inv()
- dma_cache_wback()
- dma_cache_inv()
functionality wise, especially in r4k.c i dont see any
difference between the implementation of these APIs.
Can we apply the 2.6.24

`flush' is fuzzy terminology: some people mean invalidate, others mean
write back, others mean both.

Hi,
I have ported Linux-2.6.18 kernel on MIPS24KE
processor. I am using write back cache policy.
Could you please guide me under what cases the below
cache API's are being used:
- dma_cache_wback_inv() : Could you explain what
exactly this function does
- dma_cache_wback() : This function write
